WINDOW- GRATING.

SPECIFICATION forming pari; of Letters Patent No. 341,313, dated May 4, 1886.

Application filed December 2B, 1885. Serial No. 186,873. (No model.)

.To @ZZ whom it may concern.-

Be it known that I, PETER L. BRooKLE- BANK, a citizen of the United States, residing at Saratoga Springs, in the county of Saratoga and State of New York, have invented ce1'- tain new and useful Improvements in Vindow-Gratings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains.

to make and use the same.

My invention relates to window-gratings and the object thereof is to provide a grating, the parts of which may be advanced toward each other or retracted across the path of the windowsash, and which when not in use may be entirely inclosed in boxes formed in the sides of the sash-frame.

In the accompanying drawings, in which corresponding parts are designated by similar letters, Figure l represents a window having my improvement applied thereto. Fig. 2 represcnts the grating detached from the sashframe; and Fig. 3 illustrates the grating` as it appears when in a closed position.

The sash-casing may be provided' with `an inside,outside,and parting bead forming slides between which the saslrstiles travel in the usual manner, and on each side thereof are formed boxes or pockets A, entirely within the sash-frame for the reception of the grating. Vertical slides B are cut through each side of the sash-frame, through which the gratings O and l are drawn. These gratings consist of diagonal iron bars pivoted together on the principle of lazy-tongs and attached by pivot-bolts to the upright bars D and E. Each of the upright bars D and E is provided with lugs c, a, and b. The lazy-tongs are directly pivoted to the central lug, but are connected by means of straps dd to the upper and lower lugs, c c', these straps being pivoted to the lugs, and also to the bars ofthe lazy-tongs in such a manner as to allow for the upward and downward play thereof.

The bar Eis bolted or secured within the box or pocket in the side of the sash-frame; but the bar D may be drawn in or out with facility.

It willbe obvious thatwhen the windowsash is raised thelazy-tongs may be distended until the bars D meet each other, and that when in this position the gratings may be locked or secured together by any suitable lock or fastening. Vhen thus distended, spaces will be formed above and below the lazy-tongs for the admission of air and light, while at the same time the window will be protected from intruders. The bars D will also form a support and fastening for the sash which has been raised.

Having thus described my invention, I claim and desire to secure by Letters Patentl. The combination of a sasl1-fran1c, gratings capable ofmoving in the path ofthe sash and of being retracted entirely within the sashframe, and sides of the sash frame, through which the gratings travel, as and for the purpose described.

2. The combination ofa saslrfralnediaving in each of its sides boxes or pockets, and gratings constructed of idle-tongs capable of being extended without and retracted within theboxes in the sides of the sash-casing, as and for the purpose described.

3. The combination, with a sash-frame having boxes in its sides, of the idle-tongs O, up- "right bars D and E, lugs a a b, and straps d,

as and for the purpose described.

In testimony whereof Iafhx my signaturein presence of two witnesses.

PETER L. BROCKLEBANK.
